Flux Control in a Defense Pathway in Arabidopsis thaliana Is Robust to Environmental Perturbations and Controls Variation in Adaptive Traits.

Olson-Manning CF, Strock CF, Mitchell-Olds T - G3 (Bethesda) (2015)

Bottom Line: Uncovering the general properties of biochemical pathways that influence ecologically important traits is an effective way to understand these connections.We also find that a generalist herbivore, Trichoplusia ni, modifies its feeding behavior depending on the flux through the glucosinolate pathway.The influence over herbivore behavior combined with the consistency of flux control suggests that genes controlling flux might be repeatedly targeted by natural selection in diverse environments and species.

Heat map of the direction of glucosinolate concentration change for the aliphatic and indolic glucosinolate products. The proportional change in glucosinolate concentration of the seven glucosinolate products (abbreviations on the left) following four environmental treatments (W = water deprivation, C = leaf crushing, S = soil nutrient deprivation, J= Methyl Jasmonate treatment). Colors, P -value indicators, and scale are identical to Figure 2.

fig3: Heat map of the direction of glucosinolate concentration change for the aliphatic and indolic glucosinolate products. The proportional change in glucosinolate concentration of the seven glucosinolate products (abbreviations on the left) following four environmental treatments (W = water deprivation, C = leaf crushing, S = soil nutrient deprivation, J= Methyl Jasmonate treatment). Colors, P -value indicators, and scale are identical to Figure 2.

Mentions: Each of the environmental treatments had a highly significant effect on the quantity and spectrum of glucosinolates produced (Figure 3 and Table S3). However, there are no significant genotype by treatment interactions, indicating the response to environmental treatment is homogenous in the HET and WT.
